style: remove trailing whitespace

Result of running 'hg m5style --skip-all --fix-white -a'.

X86: Keep track of more descriptor state to accomodate KVM.

X86: Explicitly use the right width in a few places that need a 64 bit value.

X86: Make the interrupt entering microcode record the value to use, not actually use it.

X86: Implement the INIT IPI.

X86: Implement IST stack switching.

X86: Use atCPL0 for accesses that are part of CPU machinery.

X86: Move where CS is set so CPL checks work out.

X86: Make exceptions handle stack switching.

X86: All x86 fault classes now attempt to do something useful.

X86: Make the long mode interrupt/exception microcode handle an error code.

X86: Make the chks microop check for the right int descriptor type.

X86: Touch up the interrupt entering microcode.

X86: Implement entering an interrupt in microcode.
